Science in the Classroom

Today we had a scientist visit our classroom! His name was Diatomic Dillon.  He was from High Touch High Tech.  We learned so much and had so much fun.  In Science we have been learning all about matter and today we learned even more!  The first experiment we did was to take skewers and poke them into a bag of water.  We got 24 skewers in before our bag started to leak! 

Do you know why the water didn't leak out?

Next we used pipettes, water and a penny.  We had to see how many drops of water we could put on the penny.  Before we did the experiment we made a hypothesis (which is what we think might happen).  Most of us thought that we could get between 1 and 6 drops of water on the penny.  When we actually did it some of us actually got between 20 and 30 drops!  We noticed that the water drops joined together.  This was similar to what happened in the experiment with the skewers.

Maxim was very careful and very engaged in his task!

Diatomic Dillon shared with us the word for when molecules stick together.  Its called cohesion.

Next we experimented with mixing different states of matter together. We mixed a solid with a liquid and got a different type of substance.  We used some of the words we had learned in our matter unit to describe what we were observing.

We also learned about density.  Watch this video and see if you can explain why Mr. Squiggly sinks when Diatomic Dillon squeezes the bottle and why he floats when he lets go.  Once you have tried to explain why watch the second video for his explanation.  Leif was able to give us a very good explanation but Mrs. Betts missed video taping it.  He was so quick with his thinking!!!!

It was another fabulous day of thinking, asking questions and learning something new!  We are super scientists.  We use all our senses to make observations and we are always asking questions.  Thank you to High Touch, High Tech for an informative and engaging science session!
